guys are uh jacob so let's get you guys

30
00:01:41,350 --> 00:01:38,310
um hi first question um i was wondering

31
00:01:43,830 --> 00:01:41,360
uh because the station is uh underneath

32
00:01:44,789 --> 00:01:43,840
the roach limit is there any tidal

33
00:01:46,950 --> 00:01:44,799
stress

34
00:01:51,830 --> 00:01:46,960
or stretching on the frame of the

35
00:01:55,350 --> 00:01:53,749
yeah that's

36
00:01:57,190 --> 00:01:55,360
that's a very interesting question and i

37
00:01:59,190 --> 00:01:57,200
have to admit i had to look up uh what

38
00:02:01,270 --> 00:01:59,200
the roach limit is and to be honest i

39
00:02:03,190 --> 00:02:01,280
don't i don't know the answer to that

40
00:02:05,109 --> 00:02:03,200
but it does highlight a very important

41
00:02:07,109 --> 00:02:05,119
point and that is that the space station

42
00:02:09,430 --> 00:02:07,119
itself is a very complex machine and

43
00:02:11,350 --> 00:02:09,440
it's taken thousands of people uh to

44
00:02:14,790 --> 00:02:11,360
build it and to run it and to make it

45
00:02:17,510 --> 00:02:14,800
work and there are there are experts on

46
00:02:18,790 --> 00:02:17,520
on every system out there so you know

47
00:02:20,229 --> 00:02:18,800
i'm guessing that there's probably

48
00:02:22,390 --> 00:02:20,239
someone out there that's very familiar

49
00:02:24,869 --> 00:02:22,400
with that limit and they could probably

50
00:02:27,030 --> 00:02:24,879
answer it for you but unfortunately uh

51
00:02:31,990 --> 00:02:27,040
yeah unfortunately rick and i aren't

52
00:02:36,390 --> 00:02:34,309
hi i'm eric and i was wondering um did

53
00:02:38,470 --> 00:02:36,400
you guys plan to be an astronaut like

54
00:02:40,150 --> 00:02:38,480
from childhood or did you come to it

55
00:02:44,550 --> 00:02:40,160
through a class you took in high school

56
00:02:48,229 --> 00:02:46,470
you know i was always interested in math

57
00:02:49,670 --> 00:02:48,239
and science when i was

58
00:02:51,270 --> 00:02:49,680
probably starting in fourth or fifth

59
00:02:53,110 --> 00:02:51,280
grade and i was interested all through

60
00:02:54,710 --> 00:02:53,120
high school on that but i never really

61
00:02:55,910 --> 00:02:54,720
thought that i could be an astronaut i

62
00:02:57,350 --> 00:02:55,920
never even knew that i could be an

63
00:02:59,589 --> 00:02:57,360
astronaut to tell you the truth till i

64
00:03:01,750 --> 00:02:59,599
was about 27 years old

65
00:03:03,350 --> 00:03:01,760
and i saw an advertisement in a magazine

66
00:03:04,869 --> 00:03:03,360
at that and they were looking for

67
00:03:06,790 --> 00:03:04,879
astronauts and people could fill out

68
00:03:09,270 --> 00:03:06,800
applications and this is when the space

69
00:03:10,710 --> 00:03:09,280
shuttle program was just beginning so

70
00:03:12,309 --> 00:03:10,720
that opened my eyes and made me

71
00:03:14,550 --> 00:03:12,319
understand that anybody can be an

72
00:03:27,910 --> 00:03:14,560
astronaut it all it takes is a lot of

73
00:03:27,920 --> 00:03:34,710
has changed since you've been on the iss

74
00:03:37,350 --> 00:03:35,750
so yeah

75
00:03:39,190 --> 00:03:37,360
yeah you can see rick groin right now as

76
00:03:40,789 --> 00:03:39,200
we speak

77
00:03:41,990 --> 00:03:40,799
yeah you know we do end up growing

78
00:03:45,190 --> 00:03:42,000
because when you you get into the

79
00:03:46,869 --> 00:03:45,200
microgravity environment you you offload

80
00:03:48,949 --> 00:03:46,879
your spine and so there is a little bit

81
00:03:50,630 --> 00:03:48,959
of growth but that uh we try and and

82
00:03:52,070 --> 00:03:50,640
actually minimize that through uh

83
00:03:53,670 --> 00:03:52,080
through exercise and things like that so

84
00:03:56,229 --> 00:03:53,680
we're constantly loading up our body as

85
00:03:57,509 --> 00:03:56,239
well and so in reality my stature has

86
00:03:59,509 --> 00:03:57,519
only probably changed about three

87
00:04:01,350 --> 00:03:59,519
percent so not as much as i was hoping i

88
00:04:07,110 --> 00:04:01,360
was hoping to hit six feet but i don't

89
00:04:11,589 --> 00:04:09,670
i'm sarah and i was wondering how you

90
00:04:17,110 --> 00:04:11,599
prevent the loss of bone density since

91
00:04:20,949 --> 00:04:18,870
hi sarah yeah that's a good question

92
00:04:23,030 --> 00:04:20,959
like mike said we exercise quite a bit

93
00:04:25,909 --> 00:04:23,040
so the types of exercise we have is we

94
00:04:27,909 --> 00:04:25,919
run on a treadmill and the way we run on

95
00:04:30,150 --> 00:04:27,919
the treadmill is we wear a harness and

96
00:04:31,909 --> 00:04:30,160
it kind of in bungie strap us to the

97
00:04:33,990 --> 00:04:31,919
treadmill so that puts a lot of load on

98
00:04:35,430 --> 00:04:34,000
our shoulders and on our legs and that

99
00:04:37,110 --> 00:04:35,440
helps with what you're talking about it

100
00:04:39,189 --> 00:04:37,120
puts load on our muscles and on our

101
00:04:41,670 --> 00:04:39,199
bones and then we also lift a lot of

102
00:04:43,990 --> 00:04:41,680
weights we have a pneumatic system

103
00:04:46,310 --> 00:04:44,000
that allows us to it's basically a

104
00:04:48,870 --> 00:04:46,320
resistive exercise device if you will

105
00:04:50,469 --> 00:04:48,880
and that also it's basically squats and

106
00:04:52,310 --> 00:04:50,479
deadlifts and bench pressing and things

107
00:04:54,870 --> 00:04:52,320
like that and again that puts load on

108
00:04:57,270 --> 00:04:54,880
our muscles which helps our bone density

109
00:04:59,430 --> 00:04:57,280
and of course a good diet in this

110
00:05:01,830 --> 00:04:59,440
constant exercise two hours every day

111
00:05:07,830 --> 00:05:01,840
helps to minimize the loss of bone

112
00:05:11,029 --> 00:05:10,150
hi i'm zoe and i have a question for

113
00:05:12,870 --> 00:05:11,039
rick

114
00:05:14,950 --> 00:05:12,880
has being able to view the world from

115
00:05:20,550 --> 00:05:14,960
the iss changed your perspective on

116
00:05:25,029 --> 00:05:23,350
hey zoey that's a that's a good question

117
00:05:27,110 --> 00:05:25,039
i don't really pay too much attention to

118
00:05:28,550 --> 00:05:27,120
world politics but i do obviously read

119
00:05:30,070 --> 00:05:28,560
the news and i understand all the

120
00:05:32,550 --> 00:05:30,080
problems that are going on in the world

121
00:05:34,310 --> 00:05:32,560
today and it does change your view being

122
00:05:36,070 --> 00:05:34,320
up here a little bit because you look at

123
00:05:38,310 --> 00:05:36,080
the world so much differently the world

124
00:05:40,390 --> 00:05:38,320
is uh is is an incredibly beautiful

125
00:05:42,710 --> 00:05:40,400
place but it's also it seems like a much

126
00:05:44,310 --> 00:05:42,720
smaller place as we go through training

127
00:05:45,590 --> 00:05:44,320
over the three years we visit a lot of

128
00:05:48,629 --> 00:05:45,600
different countries i spent a lot of

129
00:05:50,710 --> 00:05:48,639
time in russia in japan in germany even

130
00:05:52,469 --> 00:05:50,720
some time in canada and of course lots

131
00:05:54,710 --> 00:05:52,479
of time in houston in my home my home

132
00:05:55,749 --> 00:05:54,720
city so the world becomes a much smaller

133
00:05:57,510 --> 00:05:55,759
place when you go through this

134
00:05:59,029 --> 00:05:57,520
experience and you get more familiar

135
00:06:01,990 --> 00:05:59,039
with the different locations and things

136
00:06:02,790 --> 00:06:02,000
don't seem as foreign anymore to you

137
00:06:04,790 --> 00:06:02,800
so

138
00:06:06,710 --> 00:06:04,800
yeah you do change a little bit and you

139
00:06:08,150 --> 00:06:06,720
start to think that maybe it would be

140
00:06:15,749 --> 00:06:08,160
better if people just got along of

141
00:06:19,990 --> 00:06:17,909
hi i'm anne my question is for mike and

142
00:06:26,150 --> 00:06:20,000
how many hours do you of sleep do you

143
00:06:29,510 --> 00:06:27,830
that's a that's a great question and

144
00:06:31,510 --> 00:06:29,520
actually i found the up here i'm

145
00:06:33,189 --> 00:06:31,520
sleeping about as much as i do when i'm

146
00:06:35,590 --> 00:06:33,199
on the ground and that's somewhere

147
00:06:37,270 --> 00:06:35,600
between five or six hours of sleep every

148
00:06:39,430 --> 00:06:37,280
night i get up pretty much at the same

149
00:06:41,830 --> 00:06:39,440
time and and tend to go to bed at the

150
00:06:44,629 --> 00:06:41,840
same time as far as stressful sleep is

151
00:06:45,990 --> 00:06:44,639
never stressful um so it's it's actually

152
00:06:47,909 --> 00:06:46,000
pretty relaxing of course it's a little

153
00:06:49,990 --> 00:06:47,919
bit different up here we we sleep in

154
00:06:51,909 --> 00:06:50,000
sleeping bags and because there's no up

155
00:06:54,150 --> 00:06:51,919
or down we can just tie the sleeping bag

156
00:06:56,950 --> 00:06:54,160
to a wall to the deck to the to the

157
00:06:58,629 --> 00:06:56,960
overhead wherever is uh however our crew

158
00:06:59,990 --> 00:06:58,639
quarters are laid out

159
00:07:01,670 --> 00:07:00,000
so you crawl in that sleeping bag you

160
00:07:08,950 --> 00:07:01,680
kind of wrap yourself up and it's

161
00:07:13,189 --> 00:07:11,589
hi i'm a yin my question is for rick

162
00:07:15,430 --> 00:07:13,199
how is this space food and have there

163
00:07:22,950 --> 00:07:15,440
any have there ever been any attempts to

164
00:07:26,550 --> 00:07:25,029
oh the food yeah hey we we have all

165
00:07:28,629 --> 00:07:26,560
kinds of food up here we have a pretty

166
00:07:30,550 --> 00:07:28,639
wide selection of food

167
00:07:32,550 --> 00:07:30,560
and it comes in basically uh three

168
00:07:34,550 --> 00:07:32,560
different forms we have the irradiated

169
00:07:37,749 --> 00:07:34,560
food that's kind of like uh like you

170
00:07:40,790 --> 00:07:37,759
find in an mre the military folks eat

171
00:07:43,029 --> 00:07:40,800
we have the uh dehydrated food that

172
00:07:44,950 --> 00:07:43,039
basically this is uh this is actually uh

173
00:07:47,670 --> 00:07:44,960
rice pudding it's hard as a rock right

174
00:07:48,710 --> 00:07:47,680
now but we add some water to it and it

175
00:07:51,350 --> 00:07:48,720
uh

176
00:07:52,869 --> 00:07:51,360
goes back to its normal state and it's

177
00:07:54,469 --> 00:07:52,879
actually pretty good and then of course

178
00:07:55,909 --> 00:07:54,479
we have our drink bags it's really not

179
00:07:57,670 --> 00:07:55,919
much more than an envelope with some

180
00:07:59,430 --> 00:07:57,680
powder in it this is pineapple drink we

181
00:08:00,869 --> 00:07:59,440
add water shake it up and we got a good

182
00:08:04,309 --> 00:08:00,879
pineapple drink

183
00:08:06,550 --> 00:08:04,319
uh as far as food growing food mike is

184
00:08:08,230 --> 00:08:06,560
uh mike is making an attempt to grow i

185
00:08:09,189 --> 00:08:08,240
think this is a pumpkin seed that he

186
00:08:11,430 --> 00:08:09,199
brought up

187
00:08:13,110 --> 00:08:11,440
and this is kind of his uh his hobby he

188
00:08:14,950 --> 00:08:13,120
grows these little seedlings and they're

189
00:08:17,350 --> 00:08:14,960
trying trying to get him as uh

190
00:08:18,950 --> 00:08:17,360
as big as he can but it's gonna be a

191
00:08:26,710 --> 00:08:18,960
while before we actually get fruit out

192
00:08:29,029 --> 00:08:27,430
hi

193
00:08:31,110 --> 00:08:29,039
my name is luther my question is for

194
00:08:33,029 --> 00:08:31,120
mike what are the living conditions like

195
00:08:37,670 --> 00:08:33,039
on the iss is it crammed or do you have

196
00:08:40,870 --> 00:08:39,430
yeah actually the the international

197
00:08:42,870 --> 00:08:40,880
space station is quite large it's

198
00:08:44,949 --> 00:08:42,880
probably about the size of uh the inside

199
00:08:47,030 --> 00:08:44,959
of a boeing 747 or i've heard it

200
00:08:48,710 --> 00:08:47,040
described as a five-bedroom house so

201
00:08:50,870 --> 00:08:48,720
there's there's quite a bit of space on

202
00:08:53,190 --> 00:08:50,880
uh space in it uh we do have a little

203
00:08:54,389 --> 00:08:53,200
bit of uh private space we each have a

204
00:08:56,949 --> 00:08:54,399
crew quarter

205
00:08:58,470 --> 00:08:56,959
where we sleep and where we are able to

206
00:08:59,910 --> 00:08:58,480
we have our own computers in there so we

207
00:09:02,070 --> 00:08:59,920
can communicate with our families and

208
00:09:04,230 --> 00:09:02,080
friends from from that location

209
00:09:06,310 --> 00:09:04,240
and it's about the size of a small broom

210
00:09:07,990 --> 00:09:06,320
closet or for anyone that is familiar

211
00:09:10,870 --> 00:09:08,000
with a phone booth that's about the size

212
00:09:13,670 --> 00:09:10,880
of it so you do have a you do have a a

213
00:09:15,030 --> 00:09:13,680
small bit of private space but overall

214
00:09:16,470 --> 00:09:15,040
you know you don't really notice it it's

215
00:09:18,630 --> 00:09:16,480
big enough that as we're working

216
00:09:20,550 --> 00:09:18,640
throughout the day you know we don't we

217
00:09:22,310 --> 00:09:20,560
can go hours without seeing each other

218
00:09:23,829 --> 00:09:22,320
as you're working in one module and your

219
00:09:32,870 --> 00:09:23,839
crewmates are working in a different one

220
00:09:36,470 --> 00:09:34,870
and my questions for rick this is sort

221
00:09:37,750 --> 00:09:36,480
of already been asked but can you tell

222
00:09:39,590 --> 00:09:37,760
us a little bit more about how difficult

223
00:09:45,110 --> 00:09:39,600
it is to maintain your physical fitness

224
00:09:49,670 --> 00:09:47,269
yeah it's actually it is difficult and

225
00:09:51,990 --> 00:09:49,680
that it's it's very time consuming again

226
00:09:54,150 --> 00:09:52,000
like i said we spend about two two and a

227
00:09:56,230 --> 00:09:54,160
half hours a day working out

228
00:09:58,630 --> 00:09:56,240
a little more than an hour almost an

229
00:10:01,430 --> 00:09:58,640
hour and a half lifting weights or in on

230
00:10:03,110 --> 00:10:01,440
a resistive exercise device and then i

231
00:10:04,470 --> 00:10:03,120
kind of alternate some days i'll run a

232
00:10:07,110 --> 00:10:04,480
treadmill and then some days i'll

233
00:10:08,790 --> 00:10:07,120
exercise on a a stationary bicycle that

234
00:10:10,870 --> 00:10:08,800
we have here and that's usually probably

235
00:10:12,870 --> 00:10:10,880
about 40 minutes or so

236
00:10:15,509 --> 00:10:12,880
so it's the biggest problem is that it's

237
00:10:17,269 --> 00:10:15,519
time consuming and it takes up a lot of

238
00:10:18,949 --> 00:10:17,279
time for the crew member takes time away

239
00:10:20,790 --> 00:10:18,959
from science and research so some of the

240
00:10:22,470 --> 00:10:20,800
things we're trying to do is figure out

241
00:10:24,790 --> 00:10:22,480
more efficient ways for the crew member

242
00:10:27,350 --> 00:10:24,800
to exercise or try to minimize how much

243
00:10:29,190 --> 00:10:27,360
exercise the crew member needs

244
00:10:31,110 --> 00:10:29,200
and of course still stay healthy so that

245
00:10:40,310 --> 00:10:31,120
he could have more time to do science

246
00:10:42,949 --> 00:10:41,269
rick

247
00:10:45,110 --> 00:10:42,959
how big of a problem is carbon dioxide

248
00:10:47,030 --> 00:10:45,120
buildup and other spots on the iss with

249
00:10:52,069 --> 00:10:47,040
poor ventilation where carbon dioxide is

250
00:10:55,030 --> 00:10:53,750
okay yeah that's a good question carbon

251
00:10:58,069 --> 00:10:55,040
dioxide

252
00:10:59,910 --> 00:10:58,079
it's um it's not a real big problem up

253
00:11:01,990 --> 00:10:59,920
here because we have like you say we

254
00:11:04,069 --> 00:11:02,000
have quite a bit quite a number of fans

255
00:11:05,750 --> 00:11:04,079
you know we got inter-module ventilation

256
00:11:07,269 --> 00:11:05,760
we got ventilation between the modules

257
00:11:09,829 --> 00:11:07,279
we got ventilation for basically

258
00:11:11,509 --> 00:11:09,839
everything up here so it obviously mixes

259
00:11:13,269 --> 00:11:11,519
the air and keeps carbon dioxide from

260
00:11:15,590 --> 00:11:13,279
building up i remember on one of my

261
00:11:17,110 --> 00:11:15,600
first missions in in 2000 when the space

262
00:11:19,269 --> 00:11:17,120
station was only about three different

263
00:11:20,710 --> 00:11:19,279
segments the ventilation system wasn't

264
00:11:22,389 --> 00:11:20,720
fully worked out it wasn't fully

265
00:11:24,069 --> 00:11:22,399
installed yet because we were just still

266
00:11:25,829 --> 00:11:24,079
building the space station and as you

267
00:11:27,990 --> 00:11:25,839
can see these racks up here sometimes we

268
00:11:29,350 --> 00:11:28,000
would be working behind these racks and

269
00:11:31,430 --> 00:11:29,360
if you're back there for a long period

270
00:11:33,509 --> 00:11:31,440
of time you get these co2 pockets would

271
00:11:35,509 --> 00:11:33,519
build up as you're back there breathing

272
00:11:37,350 --> 00:11:35,519
and you know the symptom is you end up

273
00:11:38,790 --> 00:11:37,360
with a headache so it's nothing nothing

274
00:11:39,910 --> 00:11:38,800
usually nothing worse than you just end

275
00:11:41,509 --> 00:11:39,920
up with a headache and you kind of

276
00:11:44,069 --> 00:11:41,519
wonder why do i have a headache well

277
00:11:45,990 --> 00:11:44,079
because co2 built up where you are but

278
00:11:48,150 --> 00:11:46,000
that not really much of a problem since

279
00:11:50,949 --> 00:11:48,160
i've been up here the past uh

280
00:11:52,710 --> 00:11:50,959
three months now i've had very few co2

281
00:11:54,230 --> 00:11:52,720
symptoms so it's uh i think it's a

282
00:12:04,550 --> 00:11:54,240
problem that we've

283
00:12:08,389 --> 00:12:06,870
hi my name is eric gasteon this question

284
00:12:10,069 --> 00:12:08,399
is for mike

285
00:12:17,110 --> 00:12:10,079
what dangers do solar winds and space

286
00:12:22,310 --> 00:12:18,470
i'm sorry can you repeat the question i

287
00:12:26,629 --> 00:12:24,710
this question is from mike

288
00:12:31,430 --> 00:12:26,639
what dangers do solar winds and space

289
00:12:35,509 --> 00:12:33,030
okay yeah that's that's a great question

290
00:12:37,110 --> 00:12:35,519
and primarily the the space junk is what

291
00:12:39,110 --> 00:12:37,120
causes the most danger for us in fact

292
00:12:40,790 --> 00:12:39,120
the air force actually tracks all of

293
00:12:43,829 --> 00:12:40,800
these objects in space thousands of

294
00:12:45,430 --> 00:12:43,839
objects in space and they predict where

295
00:12:46,790 --> 00:12:45,440
in their those objects are going to be

296
00:12:48,389 --> 00:12:46,800
in their orbits and then they're also

297
00:12:50,389 --> 00:12:48,399
looking at where the space station is in

298
00:12:52,310 --> 00:12:50,399
its orbit and if it looks like any of

299
00:12:54,949 --> 00:12:52,320
those are going to meet then they'll get

300
00:12:57,430 --> 00:12:54,959
in touch with nasa and we if

301
00:12:58,870 --> 00:12:57,440
if it looks

302
00:13:01,269 --> 00:12:58,880
likely that that's going to happen then

303
00:13:02,870 --> 00:13:01,279
we might actually move the station and

304
00:13:05,590 --> 00:13:02,880
so that means changing its orbit a

305
00:13:06,949 --> 00:13:05,600
little bit boosting it up and if if

306
00:13:08,710 --> 00:13:06,959
there's not enough time to do that

307
00:13:11,110 --> 00:13:08,720
however then we might actually have to

308
00:13:13,269 --> 00:13:11,120
go down to our soyuz vehicle which is uh

309
00:13:15,030 --> 00:13:13,279
what we would use to come home in

310
00:13:16,550 --> 00:13:15,040
just in case there is any kind of a

311
00:13:24,150 --> 00:13:16,560
strike like that and we needed to get

312
00:13:27,670 --> 00:13:26,069
yeah i'm andrew uh this question's from

313
00:13:29,829 --> 00:13:27,680
mike

314
00:13:35,190 --> 00:13:29,839
do you have any recreational time and if

315
00:13:38,629 --> 00:13:37,110
yeah so you saw some of the things i

316
00:13:40,470 --> 00:13:38,639
like to do uh during our free time and

317
00:13:42,550 --> 00:13:40,480
we do have some free time our days are

318
00:13:44,150 --> 00:13:42,560
pretty full we get a few hours each

319
00:13:45,430 --> 00:13:44,160
night and then uh typically on the

320
00:13:47,910 --> 00:13:45,440
weekends we'll have a little bit of

321
00:13:49,030 --> 00:13:47,920
extra time there for for recreational so

322
00:13:50,389 --> 00:13:49,040
you know i've been playing around with

323
00:13:52,230 --> 00:13:50,399
trying to get some seeds to grow that's

324
00:13:53,670 --> 00:13:52,240
been pretty tough but one of the

325
00:13:55,110 --> 00:13:53,680
one of the things that's the most fun is

326
00:13:57,670 --> 00:13:55,120
just floating i mean it's it's a

327
00:13:59,670 --> 00:13:57,680
fantastic experience i i love doing it i

328
00:14:01,750 --> 00:13:59,680
love doing it as i work

329
00:14:03,509 --> 00:14:01,760
and so you never get tired of that

330
00:14:05,269 --> 00:14:03,519
looking out the window and and taking

331
00:14:07,189 --> 00:14:05,279
pictures of the earth is is a bunch of

332
00:14:08,389 --> 00:14:07,199
fun as well and then we do a lot of the

333
00:14:10,550 --> 00:14:08,399
same things that you guys do

334
00:14:12,550 --> 00:14:10,560
occasionally watch movies i like to read

335
00:14:14,470 --> 00:14:12,560
books so every night before i go to bed

336
00:14:15,990 --> 00:14:14,480
i'm typically reading a book as well and

337
00:14:39,590 --> 00:14:16,000
then we spend a lot of time as well

338
00:14:42,710 --> 00:14:41,030
do you feel that the training you

339
00:14:44,310 --> 00:14:42,720
received on the simulators prepared you

340
00:14:52,310 --> 00:14:44,320
for your mission or is that something

341
00:14:57,269 --> 00:14:54,550
oh yeah the training prepares us very

342
00:14:58,949 --> 00:14:57,279
well like i said before the training we

343
00:15:00,949 --> 00:14:58,959
trained i think about

344
00:15:03,509 --> 00:15:00,959
two and a half to three years for this

345
00:15:05,110 --> 00:15:03,519
mission and it was quite extensive and

346
00:15:06,550 --> 00:15:05,120
we trained a lot spent a lot of time in

347
00:15:08,230 --> 00:15:06,560
russia japan

348
00:15:10,389 --> 00:15:08,240
germany and canada because it is an

349
00:15:13,030 --> 00:15:10,399
international partnership and we train

350
00:15:15,110 --> 00:15:13,040
each other in each other's astronauts in

351
00:15:17,910 --> 00:15:15,120
in the various facilities uh the

352
00:15:19,750 --> 00:15:17,920
training is is often the training is

353
00:15:21,509 --> 00:15:19,760
kind of just in case training just in

354
00:15:23,110 --> 00:15:21,519
case we have a malfunction of some kind

355
00:15:25,030 --> 00:15:23,120
we have to be prepared

356
00:15:27,350 --> 00:15:25,040
to react to that malfunction and try to

357
00:15:29,110 --> 00:15:27,360
get the space station back back to its

358
00:15:30,069 --> 00:15:29,120
normal configuration that's a lot of our

359
00:15:34,710 --> 00:15:30,079
training

360
00:15:37,829 --> 00:15:35,990
actually i'd just like to add though the

361
00:15:39,670 --> 00:15:37,839
one thing the simulator can't give for

362
00:15:41,110 --> 00:15:39,680
you though is if you have a rack up here

363
00:15:47,030 --> 00:15:41,120
that you need to work on when we're down

364
00:15:47,040 --> 00:15:53,189
well you can but it's just a lot harder

365
00:15:57,110 --> 00:15:55,189
hi um

366
00:15:58,550 --> 00:15:57,120
thank you my name is jordan supase and i

367
00:15:59,509 --> 00:15:58,560
have a question for mike

368
00:16:01,030 --> 00:15:59,519
um

369
00:16:07,269 --> 00:16:01,040
what's the most difficult part of living

370
00:16:11,269 --> 00:16:09,430
yeah you know that's uh that's a hard

371
00:16:13,590 --> 00:16:11,279
question to answer because it's it's

372
00:16:14,949 --> 00:16:13,600
fantastic living in space uh probably

373
00:16:15,990 --> 00:16:14,959
the hardest part is being away from your

374
00:16:17,590 --> 00:16:16,000
family

375
00:16:20,150 --> 00:16:17,600
that's never easy no matter if you're on

376
00:16:21,509 --> 00:16:20,160
the earth or up here in space but

377
00:16:24,069 --> 00:16:21,519
i'm actually going to steal some words

378
00:16:26,389 --> 00:16:24,079
from rick as he's used to describe like

379
00:16:28,629 --> 00:16:26,399
what it's like going outside on an eva a

380
00:16:30,870 --> 00:16:28,639
lot of times the the simple things on

381
00:16:32,629 --> 00:16:30,880
earth become difficult up here um the

382
00:16:34,470 --> 00:16:32,639
little things like just eating your food

383
00:16:36,790 --> 00:16:34,480
you saw how we have to eat up here out

384
00:16:38,949 --> 00:16:36,800
of little packets and and so when you're

385
00:16:40,310 --> 00:16:38,959
just eating your food and and you spill

386
00:16:41,430 --> 00:16:40,320
something it ends up just going

387
00:16:43,829 --> 00:16:41,440
everywhere because it's flowing and it

388
00:16:45,910 --> 00:16:43,839
doesn't just fall down to the ground

389
00:16:47,829 --> 00:16:45,920
so a lot of those little things become a

390
00:16:49,990 --> 00:16:47,839
little bit more or easy things become

391
00:16:52,550 --> 00:16:50,000
more difficult up in space and sometimes

392
00:16:54,629 --> 00:16:52,560
as rick says too the impossible things

393
00:16:56,470 --> 00:16:54,639
become pretty easy so these racks that

394
00:16:57,990 --> 00:16:56,480
weigh hundreds hundreds of pounds that

395
00:17:00,629 --> 00:16:58,000
we would never be able to move on our

396
00:17:03,110 --> 00:17:00,639
own uh down on earth we're able to do up

397
00:17:05,110 --> 00:17:03,120
here in space quite easily so

398
00:17:07,189 --> 00:17:05,120
it's it's absolutely fantastic up here

399
00:17:12,949 --> 00:17:07,199
and really there's not there's not too

400
00:17:17,590 --> 00:17:15,829
hi my name is nicole and

401
00:17:19,590 --> 00:17:17,600
this question is for rick could you

402
00:17:25,270 --> 00:17:19,600
describe the experience of takeoff and

403
00:17:31,430 --> 00:17:28,470
yeah launch is an incredibly dynamic

404
00:17:32,549 --> 00:17:31,440
event as the words i usually use

405
00:17:34,710 --> 00:17:32,559
you know you're sitting on the launch

406
00:17:36,070 --> 00:17:34,720
pad everything is usually very quiet and

407
00:17:38,710 --> 00:17:36,080
then at launch

408
00:17:40,470 --> 00:17:38,720
it's basically it's it's kind of like

409
00:17:42,789 --> 00:17:40,480
accelerating very quickly in an

410
00:17:43,909 --> 00:17:42,799
amusement park ride or or a car i guess

411
00:17:46,390 --> 00:17:43,919
if you will

412
00:17:49,830 --> 00:17:46,400
and it's also a lot of vibrations a lot

413
00:17:52,390 --> 00:17:49,840
of noise and

414
00:17:54,630 --> 00:17:52,400
the i flew both on the space shuttle now

415
00:17:56,390 --> 00:17:54,640
and on the soyuz rocket and one of the

416
00:17:58,150 --> 00:17:56,400
things the space shuttle jumps off the

417
00:18:00,150 --> 00:17:58,160
launch pad a lot quicker but the soyuz

418
00:18:02,950 --> 00:18:00,160
rocket is very dynamic during staging in

419
00:18:04,710 --> 00:18:02,960
that when one stage burns out you kind

420
00:18:06,230 --> 00:18:04,720
of get thrown forward in your seat and

421
00:18:08,310 --> 00:18:06,240
then when the seconds the next stage

422
00:18:10,630 --> 00:18:08,320
lights you get thrown back in your seat

423
00:18:13,750 --> 00:18:10,640
and then again the vibrations pick up so

424
00:18:15,750 --> 00:18:13,760
it's a very dynamic time there's

425
00:18:17,270 --> 00:18:15,760
on the soyuz vehicle there's not very

426
00:18:18,950 --> 00:18:17,280
good windows to look out but on the

427
00:18:20,630 --> 00:18:18,960
space shuttle it was a great view as we

428
00:18:21,669 --> 00:18:20,640
used to fly up the east coast so i used

429
00:18:22,710 --> 00:18:21,679
to be able to look out the window and

430
00:18:24,390 --> 00:18:22,720
see the whole

431
00:18:26,070 --> 00:18:24,400
basically the whole east coast so it was

432
00:18:28,070 --> 00:18:26,080
a fantastic view

433
00:18:30,230 --> 00:18:28,080
and the entry on the shuttle i only have

434
00:18:31,990 --> 00:18:30,240
that experience at this point was uh not

435
00:18:33,669 --> 00:18:32,000
much different than uh flying in an

436
00:18:35,510 --> 00:18:33,679
airplane because you're more in an

437
00:18:37,190 --> 00:18:35,520
airplane configuration

438
00:18:38,630 --> 00:18:37,200
uh and it was kind of interesting

439
00:18:40,070 --> 00:18:38,640
because you would start out weightless

440
00:18:42,230 --> 00:18:40,080
and then there's the lower and lower you

441
00:18:43,990 --> 00:18:42,240
got slower and slower you got the

442
00:18:46,070 --> 00:18:44,000
gravity would kind of slowly pull you

443
00:18:47,990 --> 00:18:46,080
into your seat so you just felt heavier

444
00:18:49,909 --> 00:18:48,000
and heavier and heavier until you landed

445
00:18:51,830 --> 00:18:49,919
and then you felt very very heavy

446
00:18:53,510 --> 00:18:51,840
because you're in a one gravity or one g

447
00:18:59,110 --> 00:18:53,520
field for the first time in several

448
00:19:02,390 --> 00:19:01,190
hello my name is ted and my question is

449
00:19:03,830 --> 00:19:02,400
for mike

450
00:19:05,830 --> 00:19:03,840
what takes place in the event of a

451
00:19:10,870 --> 00:19:05,840
medical emergency that may require

452
00:19:14,549 --> 00:19:12,390
yeah that's a that's a great question so

453
00:19:16,870 --> 00:19:14,559
we actually have quite a bit of medical

454
00:19:19,669 --> 00:19:16,880
equipment on board the the space station

455
00:19:21,270 --> 00:19:19,679
uh for just about any any contingency

456
00:19:23,110 --> 00:19:21,280
and we all have to go through quite a

457
00:19:24,470 --> 00:19:23,120
bit of training on being a medical

458
00:19:26,070 --> 00:19:24,480
officer up here

459
00:19:28,630 --> 00:19:26,080
now we're very fortunate in that our

460
00:19:31,190 --> 00:19:28,640
commander oleg kotov russian cosmonaut

461
00:19:32,950 --> 00:19:31,200
he's also a doctor and so it's certainly

462
00:19:34,950 --> 00:19:32,960
nice when you when you do have a doctor

463
00:19:36,390 --> 00:19:34,960
on board so that if there is that kind

464
00:19:37,990 --> 00:19:36,400
of an emergency

465
00:19:40,230 --> 00:19:38,000
he's here to help out but on the other

466
00:19:42,630 --> 00:19:40,240
hand if there's not we have doctors on

467
00:19:44,710 --> 00:19:42,640
the ground as well and they're there

468
00:19:46,230 --> 00:19:44,720
ready to help us out so if someone gets

469
00:19:47,830 --> 00:19:46,240
seriously injured what we're going to do

470
00:19:49,909 --> 00:19:47,840
is we're going to work together with

471
00:19:51,510 --> 00:19:49,919
that doctor on the ground to try and

472
00:20:00,950 --> 00:19:51,520
figure out what's the best course of

473
00:20:04,710 --> 00:20:02,710
we've come to the end of our questions

474
00:20:07,110 --> 00:20:04,720
in the end of our wonderful program with

475
00:20:18,549 --> 00:20:07,120
